ABSTRACT
Over the past few years, much attention has been paid to the domains of quantum computing and
quantum cryptography. Both quantum computing and quantum cryptography have huge potential, and
when they are ultimately deployed in totality will require massive changes in the state of information
security. As of late 2005, quantum cryptography is still an early commercial opportunity; however, actual
commercial quantum computing devices will not appear on the scene for another 15 to 25 years. This
chapter provides a brief overview on the topic of quantum cryptography and the effects it will have on the
information security industry.
